hey man. Sounds like it could be a vaccum leak. My SS did something similar after I installed my ls6 intake. It turned out to be that the intake wasnt completley sealed on one of the ports. Also my guy Don (slowhawk) replaced all of the o-rings on the injectors too. and bam it fixed it. Also it could be your MAF might be pretty damn dirty too.
after you did your longtubes did you delete your cats or no. If so your rear o2s need to be tuned out.
